摘要
通过对1000MW超超临界火力发电机组的低压加热器疏水系统的研究,针对性地提出了3种不同的布置方式。运用热量法对其进行热经济性的理论分析与计算,结合机组的实际运行情况,对各个方案展开比较论证。认为6号低加采用疏水泵向前打,7号、8号低加使用外置式疏水冷却器的疏水连接方式热经济性较好,安全可靠,设计合理。
Through the study of low pressure heater drain system in 1 000MW ultra-supercritical thermal power units, three different arrangement ways are proposed. The thermal economy of the unit is theoretically analyzed and calculated by the use of heat method, combined with the actual operation condition of the unit. Each plan is compared. The drain connection that No. 6 low pressure heater uses the drain pump forward and No. 7 and No. 8 low pressure heaters use external drain coolers is economical, safe and reliable, reasonable design.
